Britney Spears ends up trouser-less on night out with Paris Hilton

Britney Spears ended up trouser-less during a night out with Paris Hilton over the weekend.

After winning $10,000 on a blackjack table at a casino, newly single Britney met up with Paris at the Tryst nightclub in the Wynn hotel.

The two were seemed to be such having a good time - laughing and dancing together - that Britney whipped off her satin trousers and tied them around her neck. She spent the rest of the evening in just fishnet stockings and a white satin blouse.

Onlookers revealed: “[Kevin Federline] has been partying and she feels she deserves to enjoy herself too.”

“The girls were inseparable. Britney looked so happy. They hit the dancefloor at nightspot Tryst with a vengeance. ”

The following night, Paris was spotted with a drunken James Blunt at the Tao nightclub at a Jay-Z gig but they insist they’re just friends. Singer-songwriter Joshua Radin was also at the gig and he has revealed she only had eyes for one person: “Paris Hilton …was sitting next to me the whole night. Seriously, next to me, like our legs were touching for a good 5 hours. Now don’t get the wrong idea. She never once said hello, nor even looked in my direction. Five hours. And it was unreal to watch. She must have pulled a compact out of her bag every 6 minutes to stare at herself and pose while Jay-Z was performing 18 inches from us.”

He added that when Jay-Z left the stage, Paris took his place: “Paris, who had been swilling straight vodka .. for hours, gets up on stage, has the people in charge throw her ‘record’ on the house stereo for her to lip sync two of her songs. She gets up on the stage, pukes, leaves… I find the music business charming.”
